Hi Friends
I have just successfully installed 1GB RAM in my Time Pc running on XP 3 to add to the IGB RAM already there and had intended to install a further memory module, to bring the total up to 3GB. I thought I might as well while upgrading but when I took the PC case off there is only room for a total of two modules although the specs said four spaces are available. There are two further 'beds' (?) with holes for two more slots though. Is it possible and worthwhile fitting the further RAM ? Can I fit a further expansion slot? Thanks for your help.

Short answer: adding physical DIMM sockets is not a consumer-level repair — the extra "beds" or holes seen on many OEM boards are usually unpopulated PCB footprints or mechanical features, not empty plug‑in slots. Practical routes are replacing the motherboard/system or using higher‑capacity modules that the board actually supports.

How to confirm the real slot count: a true DIMM socket is a plastic housing with retention clips and visible gold contacts. If those are missing, it is not a usable slot. The board BIOS/UEFI will report slot population; on Windows, System Information (msinfo32) or a tool like CPU‑Z (SPD tab) shows each populated slot. To identify the exact motherboard model (so the manual and per‑slot limits can be checked), run:

wmic baseboard get Manufacturer,Product,Version,SerialNumber

Then consult the board manual for supported RAM type, per‑slot maximum and population order.

Practical upgrade tips: match RAM type, speed and voltage to the manual; install matched modules to preserve dual‑channel mode — mixing sizes often works but can reduce memory bandwidth. Ensure the board supports the desired per‑slot capacity before buying larger sticks. Follow safe handling: power down, unplug, discharge static, align the notch, and press each stick until both clips click. If larger modules are not recognised, check for a BIOS update.

Notes on earlier replies: correctly cautioned that modifying the PCB to add sockets is impractical and risky. ’s comment about OS memory limits is relevant — confirm the operating system’s addressing capability before investing in higher total RAM.

Adding ram expansion slot is not an easy or risk free task as it require too play with your motherboard. I suggest you to purchase 2 memory modules of 2 GB.

Yeah, go ahead and get 2 sticks of 2gb RAM, however if you're running 4gb's of RAM you will have to run a 64bit OS so you can use the 4gb's.

Thanks for your heklp guys, will probably go for 2GB stick.
